Patent GB-562573-A (GB)
Title: Process to provide plastic surfaces with printings, colourings, or the like
IPC: B44C1/175
Filed: 1943-10-01
Abstract: A method of printing or colouring thermoplastic or thermosetting plastic materials consists in pressing into the plastic surface while it is in a hot and soft condition, a coloured or printed fibrous sheet, e.g. of paper, so that the surface fibres of the sheet are embedded in the plastic, and after cooling and hardening of the plastic, moistening the sheet and removing the unembedded portions thereof.  The impressed colour or print has a mat appearance and may have a misty appearance due to some of the surface fibres of the sheet being only partly embedded and having parts protruding from the plastic surface.  These protruding fibres may be rendered transparent and invisible by rubbing the impression with oil or by coating with a lacquer.  The method may be carried out during the moulding of the plastic article, by opening the mould while the plastic is still hot and soft, applying the colour or print-bearing sheet, and again pressing, or the sheet may be placed in the mould and the moulding material pressed thereon.  If the method is to be applied to curved plastic surfaces, the colour or print bearing sheet may be first secured to a cardboard support previously shaped while wet to the shape of the plastic surface.  Relief impressions may be produced if the moulding tool is engraved in intaglio to correspond with the print on the sheet, or if the sheet is stuck to a cardboard backing previously correspondingly engraved in intaglio.

Title: Improvements in or relating to polymers of acetyl triallyl citrate
IPC: C08F18/08
Filed: 1963-04-25
Abstract: Solid fusible polymers of acetyl triallyl citrate are prepared by polymerizing acetyl triallyl citrate in an aromatic solvent selected from toluene, ethylbenzene, xylenes and bromobenzene in the presence of an organic peroxide at 95 DEG  to 115 DEG  C. for 7 to 10 hours. The polymers are said to have a degree of polymerization of 4 to 14. The peroxide may be t.-butyl perbenzoic acid or benzoyl peroxide. The polymers may be precipitated from the reaction mixture by methanol, ethanol or isopropanol, and used for moulding, coating, impregnating and laminating and cured to a thermoset product.  In examples acetyl trially citrate is polymerized in toluene in the presence of t.-butyl perbenzoic acid, and recovered by precipitation with methanol or isopropanol, and the products mixed with titanium dioxide, zinc stearate and t.-butyl perbenzoate and moulded, or dissolved in an acetone/toluene mixture to give a coating composition. Specifications 863,793 and 941,079 is referred to.

Filed: 1963-04-26
Abstract: 1,027,066. Article engaging devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 26, 1963 [April 27, 1962], No. 16506/63. Heading B8H.  The jaws 6, Fig. 1, of an article-engaging device are moved outwards to engage a load 9 by a cam 23 rotated by a unidirectional ratchetwheel 21 and pawls 22, Fig. 4, which is driven by a counterweight 13, Fig. 1, to which a lifting device is attached by a rod 17. As it is lowered the lifting device is guided on to the load 9 by a bell-shaped member 8. The counterweight 13 continues to descend after the rest of the device has come to rest and in so doing rotates the ratchet wheel 21 by means of a pin 18 which moves in a helical slot 11a in a sleeve 11 to which the ratchet wheel is attached. This rotation drives the cam 23 anticlockwise in Fig. 4 and moves the jaws 6 into engagement with the load against the resistance of springs 24. As the device is raised the counterweight moves upwards until it abuts a plate 2, Fig. 1, and in so doing rotates the sleeve 11 and the ratchet wheel 21 clockwise as seen in Fig. 4. This rotation does not turn the cam 23 and so the jaws remain in engagement with the load which is raised. When the load is set down a second counterclockwise rotation occurs which this time turns the cam 23 to allow the jaws to disengage from the load. The amount by which the cam 23 turns can be adjusted by providing washers 25, Fig. 1, of various thicknesses.
Patent GB-292591-A (GB)
IPC: G05G17/00
Filed: 1928-06-07
Abstract: 292,591. Sure-Guard Corporation, (Assignees of Schauman, K. 0., Yancey, S. R., and Mifsud, J. L.). June 23, 1927, [Convention date]. Wheel-guards.-A spring relay device adapted for example to actuate brakes and signals on a motor car or to break the ignition circuit thereof by the action of the bumper comprises a slide rod which is moved by a spring upon the breaking by an electromagnet of a toggle which when in the normal straightened position holds the spring in compression. A spring 14 surrounding the slide rod 11<1> normally abuts on the end of a casing 10 and on an abutment 12 attached to the rod 11<1>. The links 15, 16 of a toggle are connected together by a pin 17 and respectively to the casing 10 and the abutment 12 by pins 18, 19, the pin 19 sliding in a slot 20. A pair of links 21 connects the pin 17 to a pin 23 slidable in a short slot in a block 22 and in a longer slot 25 in the casing 10. The block 22 is connected to the core of a magnet 27. The circuit for the magnet includes contacts 28 and a connector 32. Normally the parts are in the position shown, the magnet being de-energized and the spring 14 held compressed by the toggle 15, 16. When the mechanism is used in connection with an automatic stop device for vehicles, the circuit of the magnet 27 is completed by the action of the bumper. The pull on the link 21 exerted by the magnet core then breaks the toggle and permits the spring 14 to expand and move the slide rod 11<1> which may be a brake rod. The ignition circuit of the car may include a contact 37 on the abutment 12, a fixed contact 35, a wire 34, and the connector 32. The contacts 37, 35 are thus separated to break the ignition circuit when the toggle is broken. Visible or audible signals may also be operated.

Title: Improved manufacture of thymol
IPC: C07C37/00
Filed: 1922-06-15
Abstract: Thymol is prepared by sulphonating m-cresol under conditions suitable for producing a polysulphonic acid, such as the di-or even tri-sulphonic acid, which is then condensed with isopropyl alcohol, the sulphonic groups split off and the thymol steam-distilled. According to an example m-cresol is treated with oleum, containing 88 per cent total sulphur trioxide, first at 100 DEG  C. and then at 150 DEG  C.  A solution of isopropyl alcohol in sulphuric acid is run in and the mixture maintained at 80-90 DEG  C. for several hours.  It is then heated to 130 DEG  C. and a current of steam passed in, the thymol distilling off.  A small quantity of by-product may be removed by solution of the thymol in alkali.  A little isomeric thymol, melting at 114 DEG  C., is also formed.

Title: Rubber bonded asbestos and process of making same
IPC: C08K7/12
Filed: 1931-06-09
Abstract: A rubber bonded mass of asbestos fibres is made by heating a mutual aqueous dispersion of asbestos fibres and colloidal rubber particles with a protective colloid, and, if desired, an additional potential coagulant, to a temperature above approximately 65 DEG  C., without agitation, thereby causing coagulation, and thereafter removing the water without changing, in one plane at least, the relative position of the fibres, and then compacting the mass.  In an example, 3 to 5 per cent asbestos is dispersed in water containing a small amount of caustic soda, and, if desired, admixed with pigments, fillers such as zinc oxide, and sulphur, and latex containing a protective colloid such as h moglobin added.  The mass is poured into a receptacle which is heated and may be vibrated (but not stirred).  After coagulation the water may be removed by dessication or, in the preliminary stages, by pressure with a perforated plunger.  The resulting product is devoid of grain structure and has the same tensile strength in all directions.  Specification 377,782 is referred to.
